That's the typical response to people posting (legitimate) issues they've experienced with Firefox. "Oh, it's just you"
So let me get this straight: you are saying that since you haven't experienced memory problems with Firefox (I guess you and your computer are the gold standard or something), it is rightful to conclude that anyone who experiences memory problems with Firefox is "doing something wrong"
Mmm-k. You must be a Firefox developer, because they have the same flippant attitude about this.
That presupposes that the Fix It tool will work in the first place

I remember an ESPN interview of a retired NFL linebacker. He'd had multiple concussions in his playing days. He was quite mentally damaged, at the ripe old age of 45.
One day he went out for a drive, and when he got to his block, he couldn't recognize his own house. So he decided to just keep driving around the block, over and over. More than an hour elapsed before one of his family members spotted the car out the front window and went outside and flagged him down.
It wasn't the first time seemingly simple things/memories just completely escaped him
